The lower end of this shaft extends downwar ly and is connected in any suitable manner to the pump shaft, not shown, while its upper end is driv enin any suitable manner such as a belt and pulley or a vertica motor connected direct- 1y to the upper end of said shaft. The discharge head 10 is provided with an inwardly presented annular flange 12 on which is supported a ball bearing base 14 having a central aperture for the accommodation of the upwardly projecting shaft 11. vResting on base 14 is a base ring 15 provided in its upper end with an annular concave face for the reception of a convex portion of bearing ring 16. This ring is provided in its upper face with an annular raceway 1'? in 7Wll10h are designed to operatebearing balls 18 arranged for operation in ball pockets 19 formed in'retaining ring 20 which serves? to maintain said balls in proper spaced rela tion. A top ball race member 21 having a raceway 22 is arranged above retaining ring 20 and is supported upon bearing balls 18. A bearing ring 2d arranged above ball race member 21 is provided in its lower face with a circular seat for receiving the upper end of ball race member 21. This bearing ring is held in engagement with ball race mem-' ber 21 and locked against upward movement by a lock nut 25 which isscrew seated on the threaded portion 11 of shaft 11. A. lock pin 26 is driven downwardly through lock nut 25 and the lower end off said pin is seated in a suitable recess formed in the upper end of bearing ring 24 thereby securing said lock nut against rotation and accidental displacement. The retaining ring 20 is provided with a series of preferably tangentially disposed oil ducts or passageways 27, which traverse the ball cavities formed in said ring and are thereby divided into inner portions 28 which terminate inthe inner periphery of said retaining ring and outer portions 29 which terminate in the outer periphery of said ring. The inner periphery of the ring is spaced a suitable distance from shaft 11, thereby forming an. inner or central chamber 30 and the outer periphery of ring 20 is spaced at suitable distance from the circular casing 31 so as to form a circular intermediate chamber 32 with which the outer ends of oil ducts 27 communicate.

The lower end of circular casing 31 is closed by means of a circular flange 34 which projects inwardly from the lower end of casing 31 and forms a tight fit with the outer peripheral wall of base ring 15. The upper end of casing 31 is closed by a suitable cover lubricant.

ren ers 35 having a central opening for the accommodation of shaft 11 and lock nut 25. Casing31 is provided atspaced intervals with openings 36 which are circumferentially arranged in said. casing preferably on a level with the oil ducts 27 and serve to maintain the level of the lubricant contained within the housing at the proper height by discharging the surplus oil from said housing into the outer chamber 37 formed by casing 31 and discharge head 10. The oil in chamber 37 is allowed to return into the central chamber 30 by way of channels 38 formed radially in the u er face of bearing base member 14:. In or er to partially support the retaining ring 20 on ring 1 8 and partially relieve the bearing balls 18 of the pressure so that the race ways 17 and said bearing balls may be properly lubricated said retaining ring is provided with a series of"'"p ins39' which are seated therein and have their lower ends projecting downwardly and outwardly from the lower face of said ring and resting on the upper face of ball race memberslG as shown in Figure 5. i For the purpose of assemblage, casing 31 is preterab y thereof are flanged outwardly asindicated at 31 and are clamped together by suitable fastening devices 41., y

In the operation'of the device, assuming the shaft rotates in the direction indicated by arrow in Figure 4, the oil contained in the tangentially disposed passageways 27 is discharged therefrom into the intermediate chamber 32-by centrifugal action whereupon formed split and the split ends the oil contained in the central chamber 30 c amber 32 into-the outer chamber 37 which acts as a reservoir chamber ahd permits the oil contained therein to'cocl on so that tlio' temperature of the oil during the sperm; tion of the pump does not rise very much; The oil discharged from the central chamber 30 through the tangentially disposed passageways to bores 27 is replaced by fresh oil from reservoir chamber 37 by means of channels 38. Thus a steady circulation of oil through the tangentially disposed bores is accomplished by centrifugal action and the ball cavities in which the bearing hall's operate as well as the raceways of the ball race members are kept well supplied with The casing 31 which is stationary is spaced from retaining ring 20 llfi shaft, 11 race a. retam 79 her,
